IMPROVEW ENT EN CANS.

Specification forming part of Letters Patent No. 207,@.9L dated AugustS0, 1878; application filed f f Jun/3,1878.

To all whom it may concern:

Be it yknown that l, JOHN XV. MASURY, of N ew York, in the county ofNewYork and State of N ew York, have invented certain new and usefulImprovements in Gans orV Packages 5 and I do hereby declare thefollowing to be a n full, clear, and exact description of theinventhereof from deterioration or waste, by means of a thin soft-metaltopsuch as tin or lead foil-which may be readily ruptured or severed bythe thumb-nail'or other light pressure.

Another object is to afford complete protection to the thin imperforatesoft-metal top, and also impart additional strength to the open orsealed end ofthe can, whereby the latter will be enabled to sustain anyrequired weight or percussive force exerted against either its sides orends while in transit/u.

Another object of my invention is to provide simple means for securing athin softmetal top to a can in an airtight manner, and

obviate the necessity for any peculiar construe tion or formation of thebody of the can, and thus insuring an article simple in its constructionand of small initial cost; and to these ends my invention consists, rst,in a can or package for paints or other substances, a thin softmetaltop, secured to the open end of `the can by means of a metallic ring,which embraces the outer edge of the soft-metal top, and is soldered tothe outer surface of the can or package.

` My invention further consists in a can or package having a bea-dformed on the body of the can, near one end thereof, and a soft-metaltop .secnred'to one end of the can by a metal` llc ring or hoop, oneedge of which rests against the bead and is soldered to the outersurface y of the body of the can.

My invention further consists, in a can or package, of a tlnn softimetaltop, secured to one end of the can by a metallic ring or hoop, solderedto the outer surface or body of the can,of a slip-cover, the flange ofwhich surrounds the metallieriug or hoop, and its top serves to protectthe soft-metal top and impart additional strength to the can.

My invention further consists, in a can or package for paints or othersubstances, of the combination, with the body of the can, provided witha bead near-the open end thereof and a soft-metal top attached to oneend ci the can and secured in an air-tight manner by a ring, which seatsagainst said bead and is soldered to the bead lor outer surface of thecan, of a slip-cover, the flange of which extends over and protects thesoldered joint between the ring and surface of thc can.

My invention further consists in certain details of construction, aswill more fully appear from the speciiicat-ion and claims.

In the accompanying drawings, Figure 1 is y 1 a view, in perspective, ofmy improved can or package7 having the slip-cover removed there; from;and Fig. 2 `is a vertical section of the can and cover. Fig. 3 is anenlarged vertical section of the upper portion of the can.

A represents a can of any desired size or shape, which is preferablyprovided with a bead, a, formed near one end thereof. B is a soft-metaltop, and is composed of tin or lead foil, or equivalent material, theedge I) of which extends down to the bead a on the can. C

Vrepresents a metallic ring or hoop, which is placed over the outer edgeof the soft-metal topl and forced down against the bead a., thus servingto hold the top B securely in place. Ring or hoop C is then rigidlysecured to the outer surface of the can by soldering its lower edgethereto, as shown at c.

It will thus be observed that after the contents of the jar have beenplaced in the cau the impcrforate soft-metal top B, secured to the canby an air-tight joint, c, will prevent the ingress of air to theinterior of the can or package,and hence the contained substances areprevented from either deterioration or waste. i

The ring or hoop C extends slightly above the upper edge ot' the `bodyof the can, for a purpose hereinafter set forth.

D represents a slip-cover,composed of sheet Y' which extends over orembraces the metallic ring C, and covers the soldered joint o.

As heretofore stated, the upper edge of the fastening-ring C extendsslightly above the upper edge of the body of the can, in order toprevent the top E of the slip-cover from being forced against the thinsoft-metal top at that point Where it extends over the upper edge of thecan, and cutting or severing the soft-metal top.

From the foregoing it will be observed that an ordinary form of can maybe employedto embody my improvements, and that the contents of the canmay be readily sealed in an airtight manner by the use of a very thinsoftmetal top, which is adapted to be severed without the aid of a knifeor any special tool.

As lead or tin-foil melts -at a lower degree of heat than bar-solder, itis yimpossible to solder the edge f a top composed of such materialdirectlyto the surface of the can and form an airtight joint; but byemploying a metallic ring or hoop, which embraces and secures the edgeof the soft-metal top, and soldering the edge of the ring to the can, aperfect air-tight joint is formed Without vmelting and destroying thesoft-metal top.

When the contents ofthe can or package have been sealedin the mannerdescribed, and the slip-cover forced down snugly over the end of thecan,the soft-metal top is completely protected, and cannot be rupturedor severed by any ordinary rough usage experienced While the can isbeing handled or transported.

f The slip-cover alsoimparts additional stren gth to the can, andenables the latter to withstand great lateral pressure, thus preventingthe can from being forced out of its original shape, which would havethe ciiect of severing the soft-metal top.

By removing the slipcover the thin softmetal top may be readilysevered-by the thumbnail or torn open like an envelope, thus renderingit a slight and easy task'to remove the contents of one of my improvedpackages.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, 1s-

1. A can or package for paints or other subi stances providedv with athin soft-metal top, which is attached to one end of the can or packageby means of a separate hoop or ring, Which embraces' the edge of thesoft-metal top, and is soldered to the .outer surface of the can orpackage, substantially as set forth.

2. A can or package having a bead formed near one of its ends, incombination with a soft-metal top and a separate ring or hoop, whichembraces the edge of the soft-metal top and rests against the bead onthe can, and is soldered lto the outer surface of the can or package,substantially as set forth.

3. A can or package for paints or other substances having a soft-metaltop secured to one of its ends by a separate metallic ring or hoop,which is soldered to the outer surface of the can, in combination withaslip-cover, the ange of which extends over the fastening ring or hoop,and serves to protect the soft-metal top and impart additional strengthto the can, substantially as set forth.

4. A can or package provided with a bead near its open end, and asoft-metal top secured to said end by a separate ring or hoop, which issoldered to the outer surface of the can of a slip-cover, the an ge ofwhich extends downward over the soldered joint between thefastening-ring and can, substantially as set forth.

5. A can or package having a soft-metal top secured to one of its endsby a separate ring orhoop soldered to the can, and which extendsslightly above or beyond the edge of the can, in combination -with aslip-cover, which serves to protect the soft-,metal top, and isprevented from severingor rupturing the same by the projecting edge ofthe'fastening-rin g, substantially as set forth. n

In testimony that I claim the foregoing I have hereunto set my hand.
